Experts have discovered a quick way to tell if someone is more likely to cheat in a relationship. According to the results of a recent Oxford University study, the best way to tell if a significant other is going to cheat is to check the length of their fingers, The Mirror reports.
In the study of 600 people, they discovered that the length of the ring finger can indicate if a partner is pre-disposed to infidelity. The survey results shows that people whose ring finger is longer than their index finger have a higher chance of straying outside of the relationship. Those with index and ring fingers of equal length are more loyal.
Researchers believe that this is linked to the level of testosterone produced by the individual. Those with higher levels, they hypothesize, have an increased desire to reproduce.
The length of the index finger is set before birth, apparently influenced by the level of sex hormones the developing baby is exposed to in the womb, linking finger length to testosterone levels.
Researchers noted that while it is not a set rule for everyone, it could help identify people more likely to cheat.
“We observed what appears to be a cluster of males and a cluster of females being more inclined to ‘stray,’ when it comes to sexual relationships,” said researcher Rafael Wlodarski.
